Cinch has added new pluggable transceivers to its Stratos optical connectivity offering. These 100G transceivers provide low profile, hot pluggable, cost-effective solutions for optical fiber data links with an MPO or duplex LC connector interface. They are IEEE 802.3bm and QSFP28 MSA-SFF-8665 compliant.

TDK Corporation announces the introduction of the 250W rated TDK-Lambda RGA series of ruggedized non-isolated DC-DC converters. Capable of operating from an input voltage of 9 to 40V or 9 to 53V, the step-down converter delivers output voltages that can be adjustable from 3.3 to 15V, 3.3 to 24V or 3.3 to 40V with output currents of up to 20A. The series is designed to be used in harsh environment applications including robotics, AGVs (Automated Guided Vehicles), communications, COTS, industrial and portable battery-powered equipment.
In a 1/16th brick form factor, measuring 35.6 x 25.6 x 13mm, the converters are encapsulated to provide a higher resistance to shock and vibration. The five-sided aluminum case reduces radiated EMI and enables conduction cooling to a cold-plate for fan-less operation.
The RGA models comprises of three voltage and current combinations to support operation from 12V, 18V, 24V, 36V and 48V power sources. The wide input ranges can assist with inventory reduction programs with one part number covering multiple nominal voltages.
With efficiencies of up to 98%, power losses are minimized allowing the products to operate in harsh environments of -40oC to +110oC case temperature. The need for external output capacitance is reduced due to an optimized dynamic voltage response, thus reducing board space requirements.
The basic feature models include an output voltage adjustment pin, negative logic remote on-off, remote sense, input under-voltage, over-current and thermal protection. Full feature models are equipped with a power good signal, output voltage sequencing and the ability to synchronize the operating frequency to minimize system noise.
All models carry the CE and UKCA mark for the Low Voltage and RoHS Directives and are designed to the IEC/UL/CSA/EN 62368-1 safety standards. Evaluation boards are available for quick and easy testing.

Mitsubishi Electric US, Inc. recently launched a new Silicon Carbide (SiC) power module FMF400DY-24B. The 400A, 1200V Dual SiC MOSFET module includes an anti-parallel, low Vf, zero recovery loss, SiC SBD (Schottky Barrier Diode).
The module packages new designs into a current industry standard footprint (62mm x 108mm) for medical power supplies and general industrial applications. Designed for Vgs(on)=15V, the module is compatible with standard IGBT gate drivers and can be seamlessly incorporated into existing mechanical layouts for easy upgrades from Si IGBT technologies. The module uses Mitsubishi Electric second generation SiC MOSFET chip technologies that are ideal for applications requiring high switching frequencies. The SiC module reduces power loss by approximately 70% compared with an equivalently rated Si IGBT.
